AXL ELUBRICATOR.V

SPECIFICATION forming part of Letters Patent No. 370.811, dated October 4 1887.

' To @ZZ whom, t may concern.-

Be it known that I, JOHN CHRISTOPHER NIOHOL, of the cityof Montreal, in the district of Montreal, and Province of Quebec, Canada, have invented certain new and useful Improvements in Axle-Lubricators; and I do hereby declare that the following is a full, clear, and exact description of the same.

This invention has reference to that class of lubricators in which one end of a piece of'felt or similar material having capillary qualities is pressed against the journal to be lubricated and the otherhangs loosely in the lubricant at the bottom of the box.

Up to this time the means used for holding the felt against the journal have been actuated bysprings,which speedily become crystallizzedH by the jarring of the train, and by means of weighted devices, the construction of which is complicated and the setting up of them in the axleboxes difficult.

My invention consists of a movable frame slipped into place very easily and requiring no fastening to hold it in place, carrying a spindle on which are mounted levers weighted vat one end and carrying the lubricating-strips at the other, the construction of the levers insuring a constant steady contact of the strips against the journal.

For full comprehension, however, of the invention reference must behad to the annexed drawings7 in whichparts.

Figurel is a longitudinal vertical section of a railway-car axle-box, showing the journal and lubricating devices in side elevation; and 3 5 Fig. 2 is a transverse vertical section of such box and the journal, showing the lubricating devices in end elevation.

Similar letters of reference indicate like A is the axle-box; B, the axle; C, a frame shaped to be easilyinserted into the axle-box, and which will rest on the bottom, its ends forming supports C for a central rod, D.

E are levers, preferably of the shape shown, fulcrumed on the central rod, D, weighted at E and slotted at E2 E3.

F F are strips of felt orlike material forced through the slots El and E, which are of such size as will hold them firmly in place.

It will be seen that the weighted ends E of the levers E E must necessarily hold the upper portion of the felt firmly against the journal until the substance is worn away.

What I claim is as follows:

In a car-axle lubricator, the combination, withv the axle, of movable frame C, rod D,

' levers E E, and strips F, as and for the purposes setforth.
